OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 509,831, dated November28, 1893.

Application filed August l0, 1892. Serial No. 442,667. (No model.)

To @ZZ whom t may concern: A

Be it known that I, HENRYSTAOEY, of Indianapolis, county of Marion, andState of Indiana, have` invented certain new and useful Improvements inOil-Burners; and I do here-` by declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, in which like figures refer to like parts.

My invention relates to new and useful improvements in the constructionof oil burners, and is an improvement on the one shown and described inLetters Patent No. 173,858, granted to me April 26, 1892, and will beunderstood from the following description.

In the drawings, Figure l is a View partly in section of a stove with aburner therein embodying myimprovements. Fig. 2 is a plan View of tv hebase upon which the burner rests. Fig. 3 is a central section throughthe shell which iorms an air chamber around the burner. Fig. 4 is a planView of the burner.

In detail, l represents a stove, 2 the fire pot, and 3 the grate.

4 is a non-combnstible filling, preferably of clay,which isiilledinaroundtheburner shell 5 in a semi-plastic state, and whichprevents any draft from passing out through the grate outside of suchshell.

6 represents a suitable base, shown in detail in Fig. 2, which has acentral projecting ring 7 which lits within the cored out bottom of theburner 8 to retain it in a central position. The burner itself hasradiating arms or lugs 9 which rest on top of the base 6, and on thesearms the burner shell 5 which forms asurroundingairchamberrests.Theburner also has a circular oil chamber 10 which is connected by apipe 11 having a valve 12 therein with any suitable oil supply, thecentral part of the burner being raised, and its sides formed on anangle, this extension being centrally perforated, as shown in Figs. 1and 4. On the top of this central extension a Haring or inverted conicaldeflector 13 is adapted to rest, a projection being formed on its underside which fits in an opening in the central extension of the burner,thereby closing the same, and washers 14 may be interposed between thedeiiector and the top of the burner for the purpose of raising suchdeflector to any desired position. The burner shell 5 isformed in theshape of a cylinder with an overhanging top extending inward and thendownward, as at 15, the downward extension fitting snugly outside theburner, and has slits formed therein, thus allowing the air to pass upthrough the grate, the air chamber and through these slits. The shellforming the air chamber is formed with an 6o annular iiange 17 on itstop, and within this `rests an upward flaring extension 18 shown in Fig.1, this serving to keep the flame against the flaring sides of thedeflector, the shape of the deiiector and extension being such as toretard the fiaine and cause it to hug the deflector, and thus secureperfect combustion of the oil gas before it escapes from the top of thedeflector, thereby giving a perfect fiame above the burner and itscombustion cham- 7o ber, and one that is free from smoke, soot, andother impurities. By increasing or decreasing the number of washers uponwhich the defiector rests the space between the deilector and theextension 18 may be adjusted, 75 whereby the flame escaping from aroundthe top of the deliector can be regulated, the defiector being eitherraised up from the flaring extension 18, or will be brought into closerproximity to the same, and thereby cause the 8o fiame to decrease insize and become thin, thereby decreasing the heat and completing thecombustion of the gas.

The advantages in the construction and operation of thisburneroverthosein my former patent are numerous, the combustion beingmore perfect because it takes place within the burner before it escapesinto the fire pot of the stove, and owing to perfect combustion there isno loss of heat as there was in the 9o former device, where a certainamount of combustion took place after the gas from the oil had escapedinto the fire-pot of the stove, and through this caused to some extent asmoky and dirty llame. By the construction of the air chambersurrounding the burner, the draft is evenly divided and none escapesfrom the air chamber without passing through the combustion chamber tothe burner, and this secures a much better mixing of the air roo and gasgenerated by the oil than in the former device, and the proportion ofair mixed is just what is needed to effect perfect combustion, and thiscan be adjusted by raising or lowering the deiiector 13; hence a moreperfect fire. Owing to the manner of constructing the burner it is alsopossible to make it much lighter and smaller than in the former case,where a great number of perforations were necessary. In this burner theyare entirely done away with. Owing to the form and the manner ofsupporting and adjusting the central deflector in relation to theoutside extension of the burner shell, as before mentioned, the size ofthe darne can be regulated, and the escape of the products of combustioncan be retarded so that they will be consumed Y within the combustionchamber of the burner,and the volume of air coming into the combustionchamber be adjusted to effect a mixing with the oil gas in the properproportion to produce complete combustion.

What I'claim as my invention, and desire to secure by Letters Patent, isthe following:

1. In an oil burner the combination of a suitable oil chamber, aninverted conical deector having a solid projection below adapted to fitin a socket in such oil chamber and washers adapted to fit over suchprojection to render such deflector vertically adjustable, and a wallot' the burner surrounding such delector.

2. An oil burner, consisting of an oil chamber, an air chambersurrounding and extend- Ying higher than the same, suitable openings inthe inner wall of such air chamber for the ad mission of air into theoil chamber, a vertically adjustable deector supported above suchburner, and a Wall surrounding such de-V iiector parallel with the same,substantially as shown and described.

3. An oil burner consisting of an o il chamber set on a suitable baseand supplied with oil, such oil chamber having a central extension, asocket in such extension, Washers adapted to build up such extension, anair chamber surrounding such oil chamber and extending higher than thesame, a series of flanges extending downward from the overhanging top ofsuch air chamber tothe wall of the oil chamber, such Hanges separatedfor the admission of air to the oil chamber, an inverted bell-shapeddeiieotor with a solid projecting base adapted to t in the socket 1n theextension in the oil chamber, and a Wall surrounding such dedectorextending nearly as high as the same, parallel with and at a suitabledistance from such deflector, substantially as shown and described.

In 4Witness whereof Ihave hereunto set my hand this 28th day of July,1892.

HENRY sTAcEY.
